Asian Development Bank (ADB) is planning to scale up a satellite-based smart meters project, implemented in a village in Uttar Pradesh, as it finds it to be a win-win solution for several stakeholders, including the consumers as well as discoms.

As part of its USD 200 million loan for Energy Efficiency Services Limited (EESL) to implement various demand-side energy efficiency projects in India, the ADB assisted pilot is running in a village in Varanasi where as many as 5,000 households have got smart meters with satellite communication technology installed by EESL.

ADB is considering scaling up this project through a proposed second plan, ADB's Yongping Zhai said in a blog.

Zhai, who is the chief of energy sector group, sustainable development and climate department, said: "We have observed that smart meters bring benefits to four key stakeholders."

When more rural households install distributed solar photovoltaic panels on their rooftops, smart meters can be used as net metering -- it means surplus solar power can be transferred to the grid, allowing customers to offset the electricity bills, he said.

Also, smart meters can be used for time of use tariffs, allowing different tariffs for day and night.

For the power distribution companies (discoms), smart meters ensure accurate billing as there is no human intervention and they can remotely disconnect customers who fail to pay bills on time.

"This helps local distribution companies improve their billing and collection efficiency and thus reduce aggregate technical and commercial losses from around 30 per cent to 15 per cent," Zhai said.

Besides, they can predict power purchase requirements and thus can use energy more optimally.

Smart meters are affordable, costing about USD 35 (around Rs 2,560) to buy and another USD 35 to deploy for five years.

This is fully paid as an initial investment by EESL, which in turn gets Rs 100 (USD 1.3) per meter per month from local distribution companies out of savings realised over the expected eight-year lifespan of each device, generating a 14 per cent return on equity for EESL.

Terming it as an innovative business model -- invest-own-operate -- Zhai said it can be replicated elsewhere in India and many other developing countries that suffer from high system losses, as it does not burden local distribution companies upfront.
